             Calpine Announces Plans for $357 Million of Asset Sales

               Company Enters Into Exclusive Negotiations to Sell
           Four Power Plants Totaling Nearly 850 Megawatts of Capacity

             Advances Program to Reduce Debt, Increase Cash Flow and
                            Optimize Power Portfolio

     (SAN  JOSE,  Calif.)  /PR  Newswire - First  Call/ June 14,  2005 - Calpine
Corporation  [NYSE:CPN] has entered into exclusive  negotiations for the sale of
four  gas-fired  power  plants,  representing  nearly 850 megawatts of capacity.
These  potential  power plant  sales are part of  Calpine's  recently  announced
strategic  program  to reduce  more than $3  billion of debt by the end of 2005,
increase cash flow and optimize its power plant  portfolio.  Three of the plants
are located in the  Pennsylvania-New  Jersey-Maryland  (PJM) power  market - the
fourth is in Illinois.

     Calpine has entered into four separate, non-binding agreements for the sale
of the power plants.  Three of the four asset sale  agreements  are with Tenaska
Power Fund,  L.P.  (Tenaska).  The fourth  agreement is with Diamond  Generating
Corporation  (Diamond).  Completion of these four asset sales is dependent  upon
the  execution of  definitive  purchase and sale  agreements  for each plant and
other terms and conditions,  including regulatory  approvals.  Net proceeds from
any power  plant  sale  would be used to  reduce  debt and as  permitted  by the
company's indentures.

     "Calpine   continues   to  evaluate   attractive   opportunities   to  sell
non-strategic  power plants," stated Calpine Chief Financial  Officer Bob Kelly.
"While these are strong operating plants, they present Calpine with an excellent
opportunity  to divest of non-core  assets,  strengthen  its  balance  sheet and
retain the long-term value of the company's generating portfolio."

     The proposed power plant sales include:

     o    Ontelaunee  Energy  Center -  Located  in  Ontelaunee  Township,  this
          584-megawatt, gas-fired, combined-cycle power plant entered operations
          in 2002 and generates  electricity  for the PJM power market.  Calpine
          developed  and  managed  construction  of  Ontelaunee  and  has a 100%
          interest in the power plant. The company is in exclusive  negotiations
          with Tenaska for the sale of the plant for approximately $231 million.
          As part of the agreement,  Calpine  expects to provide  operations and
          maintenance and other energy services to Tenaska.

     o    Morris Power Plant - Calpine has a 100% interest in this 156-megawatt,
          gas-fired,  cogeneration  plant.  Located in Morris,  Ill.,  the power
          plant began  operations  in 1998 and  provides up to 77  megawatts  of
          electricity  and an  average  300,000  pounds  of  steam  per  hour to
          Equistar Chemical under long-term agreements.  Excess capacity is sold
          to Exelon Generating Company LLC and into the open market. The company
          is in exclusive negotiations with Diamond for the sale of its interest
          in Morris for approximately $82 million.

     o    Grays Ferry Power Plant - Located in Philadelphia,  this 175-megawatt,
          gas-fired,  cogeneration plant entered operations in 1998 and delivers
          electricity  to PECO Energy  Company and steam to  Trigen-Philadelphia
          Energy under  long-term  contracts.  Calpine has a 50% interest in the
          Grays Ferry  plant.  The  company is in  exclusive  negotiations  with
          Tenaska for the sale of its interest in Grays Ferry for  approximately
          $37 million.

     o    Philadelphia  Water Works Plant (PWW) - Also located in  Philadelphia,
          Calpine has an 83% interest in this  23-megawatt,  cogeneration  power
          plant. PWW generates  electricity from two standby  generation/peaking
          units,  fueled by natural  gas,  diesel and biogas.  The plant,  which
          entered  operations in September  1993,  supplies  electricity for the
          Philadelphia Municipal Authority under a long-term agreement.  Calpine
          is also in exclusive negotiations with Tenaska for the sale of PWW for
          approximately $7 million.
